From an agent perspective, there are some important questions regarding this issue: (1) how to choose a partner, taking into account its reputation and the costs associated with the partnership? (2) is it worth to manipulate information? (3) how to act in a society guided by the concept of reputation in order to achieve better results? In this paper, we present and discuss some results obtained from a reputation-based partnership formation simulator called RePart, using a simplified consumer/enterprise market scenario as a target domain. \itemrv{~} \itemcc{} \itemut{} \itemli{doi:10.1007/978-3-540-92803-4\_12} \end
